Cycling a 240 need help?

[deuce biggalow]

Alright here is the deal, the tank has been cycling now for about 3 weeks, I have live rock, live sand, added bacteria, wet/dry/ fluidized bed filter etc. I never saw a trace of ammonia. The nitrites were very high, and now they are going down, they are almost at 0, the nitrates are not really going up, I would say they are between 5-10, Is it almost ready? Should the nitrates read higher? Currently the tank has:
15 damsels, large black tang, large hippo tang, large yellow tang, small clown trigger, small niger triger, small blue jaw trigger. Thanks, Justin

consider a 3 week old tank
how many lbl of LR and live sand do you have?
I don't think it fully cycle
even though ammonia and nitrite are 0 or you never saw any ammonia (if that is the case they are not at the peak yet)I think it gonna spike soon.
the tank natural Bi-o filter can not handle those Tangs you have.
That is alot of fish for 3 week old tank
what do you cycle with?
I assume with 15 damsels
I learned my hard lession,
did you quarantine those fishs for a bout 3 weeks prior adding to the main tank?
